Our laboratory is well-known for its work on dating many objects of general as well as scientific interests.
An example of precision dating is the Dead Sea Scrolls.
Select the service menu for radiocarbon dating (14C dating), 10Be or 129I measurements The Arizona Accelerator Mass Spectrometry (AMS) Laboratory is used primarily to provide radiocarbon measurements.
We have operated an AMS laboratory at the University of Arizona since 1981, as a shared facility between the Departments of Physics and Geosciences.
The AMS Laboratory is also part of the School of Earth and Environmental Sciences.
Radioactive elements were incorporated into the Earth when the Solar System formed.
All rocks and minerals contain tiny amounts of these radioactive elements.
Radioactive elements are unstable; they breakdown spontaneously into more stable atoms over time, a process known as radioactive decay.Radioactive decay occurs at a constant rate, specific to each radioactive isotope.Since the 1950s, geologists have used radioactive elements as natural "clocks" for determining numerical ages of certain types of rocks. "Forms" means the moment an igneous rock solidifies from magma, a sedimentary rock layer is deposited, or a rock heated by metamorphism cools off.It's this resetting process that gives us the ability to date rocks that formed at different times in earth history.A commonly used radiometric dating technique relies on the breakdown of potassium (Ar in an igneous rock can tell us the amount of time that has passed since the rock crystallized.If an igneous or other rock is metamorphosed, its radiometric clock is reset, and potassium-argon measurements can be used to tell the number of years that has passed since metamorphism.
